黑龙江省德都县五大连池火山群中部的老黑山、火烧山,是该火山群中最新的两座火山,其最后喷发时间为1719—1721年。五大连池火山群位于松辽裂谷带与小兴安岭隆起交界处,四周为深大断裂所控制,火山通道则位于次级断裂交汇处。区内地层除第四系火山岩外,尚有石炭系千枚岩、板岩,白垩系砂、页岩,第三系砂砾岩及第四系松散沉积物。侵入体有华力西及燕山期花岗岩。本区火山喷发为中心式,老黑山在前,火烧山在后,脉动式溢流和韵律式爆发相间,构成面积近70平方公里的熔岩台地和比高分别为166米、70米的老黑山、火烧山两个火山
The middle of the Wudalianchi volcanic group in Dedu County, Heilongjiang Province, is the Old Montenegro and the Huosheng Mountain, the two newest volcanoes in the volcano group. Its last eruption time was 1719-1721. The Wudalianchi Volcano Group is located at the junction of the Songliao Rift Valley and the Xiaoxing’an Ridge, surrounded by deep faults and the volcanic channel at the juncture of secondary faults. In addition to Quaternary volcanic rocks in the area, there are Carboniferous phyllites, slate, Cretaceous sand, shale, Tertiary conglomerate and Quaternary loose sediments. Invasive bodies are Variscan and Yanshanian granites. The volcanic eruptions in this area are center-like. The old Montenegro is in front of the mountain, and the pulsating overflow and rhythmic explosions are in phase with each other to form a lava platform with an area of nearly 70 square kilometers and the old Montenegro of 166 meters and 70 meters respectively , Burning two volcanoes
